2016 MERCEDES-BENZ CLA COUPE clutch

!
Do not warm up the engine when the vehicle
is stationary. Drive off immediately. Avoid
high engine speeds and driving at full throttle
until the engine has reached its operating
temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta- tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! Mercedes-AMG vehicles:
avoid full-load
operation and engine speeds greater than
5000 rpm when the engine is cold. This will
help to protect the engine and maintain
smooth engine operation. Key positions
Key g
To remove the key
1 Power supply for some consumers, such as
the windscreen wipers
2 Ignition (power supply for all consumers)
and drive position
3 To start the vehicle
Vehicles with manual transmission: the
steering is locked when the key is taken out of
the ignition lock.
i If the key does not belong to the vehicle, it
can still be turned in the ignition lock. How-
ever, the ignition will not be switched on. The engine cannot be started. Start/Stop button General notes
Vehicles with KEYLESS-GO are equipped with
keys featuring an integrated KEYLESS-GO func- tion and a detachable Start/Stop button.
A check that periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehicle.This occurs, for example, when the engine is
started.
When you insert the Start/Stop button in the
ignition lock, the system needs approximately
two seconds of recognition time. You can then
use the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. Pre-requisite for
this is that:
R you do not depress the brake pedal (vehicles
with automatic transmission)
R you do not depress the clutch pedal (vehicles
with manual transmission)
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately (vehicles with automatic transmission).
If you depress the clutch pedal and press the
Start/Stop button, the engine starts immedi-
ately (vehicles with manual transmission).
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in the
ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key or
KEYLESS-GO (Y page 77)
Do not keep the KEYLESS-GO key:
R with electronic devices, e.g. a mobile phone
or another key
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short time:
R you will no longer be able to switch on the
ignition with the Start/Stop button
R you will no longer be able to start the engine
with the Start/Stop button until the vehicle is
unlocked again Driving

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
General notes Vehicles with a petrol engine:
the engine runs
at a higher engine speed during the cold start
procedure so that the catalytic converter can
reach operating temperature more quickly. The
sound of the engine may change as a result.

Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting to
5thand 6thgear, you must
press the shift lever to the right. Otherwise,
you could shift unintentionally into 3rdor4th
gear and damage the engine or transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine to
overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients. There is otherwise a risk of damaging the clutch.
! On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer, you must shift into gear
1, 2or3in good time.
This uses the engine's braking effect. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. k

This results in the vehicle being driven at
lower engine speeds and the wheels being
less likely to spin.
R gliding mode is activated automatically when
engine-internal conditions are fulfilled and
the accelerator is not depressed. At the same
time the transmission’s clutch opens and the
vehicle rolls freely using its kinetic energy. As a result great distances can be completed
without the engine brake and fuel consump-
tion reduced.
i The availability of gliding mode depends on
various factors, including the following:
R the engine and transmission temperature
R the downhill gradient
R the vehicle speed
R performing regular adaptation functions
When you depress the brake pedal, gliding
mode is deactivated, depending on pedal
pressure.
When you activate cruise control or Distance Pilot DISTRONIC, gliding mode is not availa-

R Always drive at adequate, but not exces-
sive, engine speeds.
R Change gear in good time.
R If possible, do not change down several
gears at a time.
Storing the current speed or calling up the
last stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards
